The prevalence, characterization, and classification of acute, post-traumatic, occult subcortical fractures of the knee, identified at magnetic resonance (MR) imaging, were evaluated prospectively in 120 consecutive patients first seen with acute posttraumatic hemarthrosis of the knee. The tibia and fibula bones sit above and to the sides of the talus, forming the ankle joint. Symptomatic traumatic osteochondral lesions of the knee remain a significant treatment challenge in a young active patient.5., 13. Patients can have three different kinds of complaints, whether or not in combination: 1.  |  Operative treatment of osteochondral lesions of the talus. Occasionally, a specialized test called a bone scan with be utilized to identify if the underlying bone is healthy and prepared for certain techniques.  |  cartilage injury with associated subchondral fracture but without detachment Although it is adopted for osteochondral abnormalities of the talus (1), the term lacks specificity and should be only part of a description of a more specific diagnostic entity. 81 patients (mean age 30±8 years) were evaluated in this study. This technique is suitable for younger to middle age patients with very focal areas of cartilage loss (typically less than 2 square centimeters) and where the remaining cartilage is healthy. Methods. Large post-traumatic osteochondral defects of the proximal tibia in young active patients can be challenging because total or partial arthroplasties are to be avoided. Chondral/Osteochondral Defect The talar dome has no direct muscle attachments(2); during norm… Osteochondral lesion is a general term that encompasses a variety of acute or chronic localized abnormalities of the articular cartilage and subchondral bone. [ 11] A The talus is the bottom bone of the ankle joint. Osteochondral lesions (OCLs) are focal articular injuries of the subchondral bone and the cartilage with a multifaceted cause (trauma, ligament instability, ischemic necrosis, malalignment, endocrine diseases, and others). An osteochondral defect that is in the early stages may be suitable for a repair technique to keep the native bone and cartilage. The cartilage repair techniques described were able to provide a repair tissue which closely approximates the characteristics of the naive hyaline cartilage. This process is delicate and requires optimum conditions to be routinely successful. Histological evaluations highlighted collagen type II and proteoglycan expression. Methodological variations affect the release of VEGF in vitro and fibrinolysis' time from platelet concentrates. Surgical treatment of osteochondral lesions of the talus by open-field autologous chondrocyte implantation: a 10-year follow-up clinical and magnetic resonance imaging T2-mapping evaluation. The articulation of the talar dome and the trochlear surface (tibia and fibula) supports the weight of the body. Google Scholar | Crossref | Medline | ISI Does the Application of Platelet-Rich Fibrin in Anterior Cruciate Ligament Reconstruction Enhance Graft Healing and Maturation? An osteochondral lesion of the talus (OLT) is an area of abnormal, damaged cartilage and bone on the top of the talus bone (the lower bone of the ankle joint). Some healthy flaps of cartilage can be repaired by special techniques.  This would need to be discussed in detail with your surgeon. Epub 2008 Jan 28. 71. Post-traumatic tibiotalar arthrosis remains a difficult ... Osteochondral allografts were obtained from fresh Initial x-rays are taken to check the alignment of the foot and ankle, as well as look for any bone damage. post-traumatic ankle arthropathy in seven patients. In later stages of the disorder there will be swelling of the affected joint which catches and locks during movement. Access your health information from any device with MyHealth. The joint feels unstable and won’t straighten fully. HHS The blood supply to the talus is not as rich as many other bones in the body, and as a result injuries to the talus sometimes are more difficult to heal than similar injuries in other bones. A 40-year-old with a history of recurrent patellar dislocation resulting in post-traumatic patellofemoral chondromalacia has persistent anterior knee pain and swelling 2 years after patellofemoral chondroplasty and synovectomy. It is widely accepted that chondral injuries in a weight-bearing portion of the knee may progress to osteoarthritis. Over time these cells can develop into a new form of cartilage. Numerous factors are considered when evaluating these disorders for the correct treatment and each scenario should be discussed in detail with your surgeon. Evolution in surgical technique, new biomaterials and more recently the use of BMDCs permitted a marked reduction in procedure morbidity and costs up to a "one step" technique able to overcome all the drawbacks of previous repair techniques. Average follow-up was 148 months (range, 85 to 198). doi: 10.1177/0363546509349928. Am J Sports Med. These can occur from an acute traumatic injury to the knee or an underlying disorder of the bone. Cartilage repair evolution in post-traumatic osteochondral lesions of the talus: from open field autologous chondrocyte to bone-marrow-derived cells transplantation Injury. 2010;41(11): 1196 – 1203. The defects cause deep ankle pain associated with weightbearing. An osteochondral cyst can also be present following surgery. Osteochondritis dissecans (OCD or OD) is a joint disorder primarily of the subchondral bone in which cracks form in the articular cartilage and the underlying subchondral bone. eCollection 2020 Feb. Anal Bioanal Chem. This condition is also known as osteochondritis dissecans (OCD) of the talus or a talar osteochondral lesion (OCL). They can also occur following severe trauma to the knee such as a skiing accident where the meniscus/cartilage is damaged. Management of End-Stage Patellofemoral Post-Traumatic Chondromalacia with Fresh Osteochondral Allograft. Epub 2012 Dec 5. Introduction. The mean depth of the lesion was 4.0 ± 0.9 mm. Osteochondral lesions are commonly the result of excessive force going through the knee. USA.gov. A review of osteochondral lesions of the talus. 2019 Dec;411(30):7943-7955. doi: 10.1007/s00216-019-02148-8. This condition is also known as either osteochondritis dissecans (OCD) of the talus or as a talar osteochondral lesion (OCL). Several types of transplants have been described, including taking small plugs of bone and cartilage from other locations in the knee and filling this defect. Clipboard, Search History, and several other advanced features are temporarily unavailable. osteochondral-defect The aims of this study are to describe evolution in cartilage repair from open field autologous chondrocyte implantation to regeneration by arthroscopic bone-marrow-derived cells (BMDCs) "one step" technique; to present the results of a series of patients consecutively treated and to compare in detail the different techniques used in order to establish the advantages obtained with the evolution in cartilage regenerative methods. 2019 Sep;53(5):372-375. doi: 10.1016/j.aott.2019.04.002. 2009 Apr;26(2):205-26. doi: 10.1016/j.cpm.2009.01.003. Please enable it to take advantage of the complete set of features! This can often take months until a suitable donor is available. This site needs JavaScript to work properly. Often what is required is the use of a fresh donor graft of bone and cartilage that is specifically matched to the size and dimensions of the defect. Injury. One less common or documented etiology is post traumatic hallux valgus. Epub 2019 Nov 11. Despite the growing body of literature supporting the use of tibial allograft transplantation to treat severe post-traumatic or degenerative osteochondral lesions, there is a relative paucity of literature reporting on its surgical technique. Purpose:This study aimed to evaluate the clinical outcome and graft survival following coronoid reconstruction with osteochondral bone grafts for post-traumatic coronoid … Giannini, S, Buda, R, Cavallo, M. Cartilage repair evolution in post-traumatic osteochondral lesions of the talus: from open field autologous chondrocyte to bone-marrow–derived cells transplantation. Surgery was indicated in osteochondral lesions of the talar dome rated as Chronic Type II or IIA. Giannini S, Buda R, Battaglia M, Cavallo M, Ruffilli A, Ramponi L, Pagliazzi G, Vannini F.
